Application filed March 5, 1912. Serial No. 681,692.

To all whom it may concern Be it known that 1, JOHN F. MULLANEY, acitizen of the United States, residing at 110 East Pikes Peak avenue, inthe city of Colorado Springs, in the county of El Paso and State ofColorado, have invented new and useful Improvements in Strainers forFluids, of which the following is a specification.

My invention relates to improvements in strainers for fluids in whichthe strainer fabric or filtering member is supported in a dome-form orupright position as of a cone with a dome-shaped apex, so that thedebris or rejected articles to be eliminated, pass down by the side ofthe strainer fabric to a trap below it, instead of being retained in thebottom of a sagging strainer fabric in the usual form; and the objectsof my invention are, in part; first, to provide in the bottom of thestrainer receptacle, a strainer that will eliminate from the liquid orthe fluids-ll debris, germs, and foreign matter desired to be removedfrom the fluid; second, to provide a trap to retain said debris, germsand foreign matter from the liquid or the fluid; third, to provide meansfor readily assembling and disassembling the strainer apparatus with andfrom its proper receptacle, and the receptacle from connected appliance;fourth, to provide a strainer that is sanitary and easily cleaned.

l attain these objects by means of mechanism and appliances illustratedin the accompanying drawing, in which, Figure 1, is a perspective detailof the bottom part of the strainer. I

Fig. 2, is a perspective of a strainer for gasolene. v

Fig. 3 is an upright section of a strainer for water'and to be used on afaucet.

Similar figures refer to similar parts throughout the several views.

The cone shaped support with its covering strainer-fabric and theinclosing receptacle, and having the walls inclosing the recess 40,about the base of said support, and adapted to receive and retaindebrls, constitute the principal parts of my invention.

The principles of my invention are carried out invaried. forms to suitthe peculiar requirements for straining fluids of various kinds and ofvarious consistencies including cream, water, fruit juices, air andgases.

Projecting upwardly from the bottom of each of my forms of strainer asherein shown in Figs. 1, 2, 3, is a common cone shaped shell support 29,here shown detachably secured to an upwardly projecting flange 30, whichis integral with the bottom of the strainer.

Over the supporting shell 29, in Fig. 2, is shown suspended a strainer23', of chamois skin orother suitable skin or fabric provided to extendbelow the top 22, of the upward projecting annular flange 30, or belowthe bottom perforations 20, and which is secured to the bottomof thecone-shaped shell 29., by means of the retaining ring 28, being presseddown upon it and holding it in place by compression, by gravitation, andby the spring of the said ring.

The ring 28, as shown, is an open ring and has a tendency, by its owncontraction,

to bring its ends together at 31, and may be forced partly open whenforced down to the largebase of the cone 29.

In Fig. 1, part of the strainer fabric 23, is shown covering theapex-24L, and part of it is shown removed to disclose thesupportingcone-shaped shell, 29, with its numerous small orifices 25.

Part of the retaining ring 28, in Fig. 1 is also shown removed,disclosing the top edge 27, of the upward projecting annular flange 30,and the outlet 52. i

Fig. 2 is especially for gasolene. Any foreign matter in the gasolene,such as water or other liquid or foreign particles having a greaterspecific gravity than gasolene, or forming larger globules, will slideoff of the strainer 23, in the cavity of receptacle 6, and

' settle down into the trap beneath the retaining ring 28, which isbelow the top edge 22, of the upper projecting annular flange 30, whereit will be retained without possible means of escaping to the outlet 52.

Any particles of water or debris coming into contact with strainer 23,above the line of the top 22, of the flange 30, will glance oil and rolldown the side tothe quiet recess 40.

lhe nose 26, of the gasolene strainer Fig.

2, is provided to fit into the opening in the tank 32, to prevent thestrainer from careenfilm shoulder rest 19, is provided to support thestrainer on'the receptacle 34.

In the. bottom of the strainer" receptacle in Fig. 1 is the upwardprojecting annular flange 30, integral with the bottom part of thereceptacle, which is the floor of the annular trap recess 40. Removablymounted upon this flange is the perforated hollow shell 29, having theperforations 25, 25, provided to allow the strained fluid from thereceptacle topass into the outlet. The lower edge of this cone-shapedshell has no perforations below the top edge 27, of the flange 30, asthere can be no liquid pass out downwardly below the edge 27.

The strainer fabric, proper, 28, covers the shell 29, and maybe one ormore thicknesses of cloth or other fabric and may be line or coarse tosuit the desired requirements and maybe in the form oitheplain-cloth ormay be formed in the shape of the cone as desired and is more preferablyof washable or cleanable material.

Over the cone-shaped shell, 29, with its dome-shaped apex 24, and the'strainer-,

' or semi-liquid substance, I omit the strainer fabric, 23, and theretaining ring, 28, en-

' tirely, and use the perforated hollow shell,

29, as a sort of colander.

In the colandering of fruit, seeds, etc, will settle down into theannular trap-recess 40, and out of the way of the thick liquid. I applyit in the same way for animal pulp as I do for fruit pulp or other denseliquids.

In Fig. 3 is shown a form of the strainer receptacle with the wall 7curved, and an upward projecting. annular flange 30, surmounted by aperforated supporting shell 29, over which is stretched the strainerfabric 23, and secured around the bottom by the large heavy retainingring 28, This form of receptacle 3, is preferably made of some whattransparent material, so asto disclose collected debris, and has alargeintake 2, provided to allow easy access to its interior.

In the supporting shell 29, are perforations 16, 16, to allow thepassage of fluids to the outlet 11.. v

The opening 2, of the neck 13, of the receptacle, in Fig, 3, is shownclosed by a pliable gasket 3, into which is inserted the nose 15, of thesupply pipe 9, having the shut ofl 17, and is represented as being heldin place by the elasticity and friction of the gasket 3, but it may haveother'desirable means for securing it over the outlet 10.
